Question
Let us consider two water columns at different temperatures, one being at 40oC and the other being at 20oC. As both the water columns are separated by a glass wall of area 1m by 2m and a thickness of 0.003m. Calculate the amount of heat transfer. (Thermal Conductivity of glass is 1.4 W/mK)

- The Diamond Ring Solution. The processing chip on the computer that controls the navigation equipment on your spacecraft is overheating. Unless you fix the problem, the chip will be damaged and the navigation system will shut down. You open the panel and find that the small copper disk that was supposed to bridge the gap between the smooth top of the chip and the cooling plate is missing, leaving a 2.0 mm gap between them. In this configuration, the heat cannot escape the chip at the required rate. You notice by the thin smudge of thermal grease (a highly thermally conductive material used to promote good thermal contact between surfaces) that the missing copper disk was 2.0 mm thick and had a diameter of 1.0 cm. You know that the chip is designed to run below 70 °C, and the copper cooling plate is held at a constant 5.0 °C. (a) What was the rate of heat flow from the chip to the copper plate when the original copper disk was in place and the chip was at its maximum operating…arrow_forwardAn electric heater in the form of a horizontal disc 0.192 m in diameter is used to heat the bottom of a tank filled with resting engine oil to a temperature of 5 °C.

- Thermal Conductivity Problems: a. A wall is made of firebrick 6 inches thick and has a 50°C difference in temperature both sides. Calculate the heat transferred through the wall if the thermal conductivity of the brick is 0.65 BTU/hr-ft- oF. b. Compute the amount of heat flow per second through an iron plate 2 cm thick and the area of 5000 cm² if one face has a temperature of 150°C and the other face is 140°C? The thermal conductivity for iron is 80 W/m-K.arrow_forwardA picture window has dimensions of 1.40 m * 2.50 mand is made of glass 5.20 mm thick. On a winter day, the temperatureof the outside surface of the glass is -20.0°C, while the temperatureof the inside surface is a comfortable 19.5°C. (a) At whatrate is heat being lost through the window by conduction?
